Description

L'invention se rapporte à un dispositif d'appui arrière prévu pour être intégré à un ensemble de retenue d'une chaussure sur un engin de glisse ou de roulage. Le dispositif peut aussi être intégré à une chaussure.The invention relates to a rear support device designed to be integrated into a restraint system shoe on a gliding or rolling machine. The device can also be integrated into a shoe.

Ce type de dispositif est utilisé pour la pratique de sports où la chaussure prend place sur un engin comprenant une planche, un châssis, ou autre. C'est le cas notamment pour le surf sur neige ou snowboard, le ski, la raquette à neige, le patin ou la planche à roues.This type of device is used for the practice of sports where the shoe takes place on a machine comprising a board, chassis, or whatever. This is particularly the case for the snowboarding or snowboarding, skiing, snowshoeing, skate or wheel board.

Traditionnellement un dispositif d'appui arrière comprend une manchette, laquelle présente une face avant prévue pour recevoir l'arrière du bas de jambe d'un utilisateur. La manchette est courbée de façon que la face avant soit concave transversalement. Ainsi l'utilisateur peut d'une part prendre des appuis arrière, et d'autre part prendre des appuis latéraux.Traditionally a rear support device includes a cuff, which has a front face provided for receive the back of a user's lower leg. The cuff is curved so that the front is concave transversely. So the user can on the one hand take rear supports, and on the other hand take supports side.

Il est apparu que pour certains exercices de style, il est souhaitable de prendre des appuis arrière et d'avoir une grande liberté latérale pour les mouvements du bas de jambe.It appeared that for certain style exercises, it is desirable to take rear supports and have great lateral freedom for lower leg movements.

Il a donc été proposé de réduire la courbure transversale d'une portion supérieure de la manchette.It has therefore been proposed to reduce the transverse curvature of an upper portion of the cuff.

Lorsque la portion supérieure de sa manchette présente une face avant dont la courbure transversale est réduite, le dispositif d'appui permet d'exécuter des figures qui exigent de fortes inclinaisons latérales du bas de jambe. Cependant ce dispositif rend les appuis arrière moins précis, ce qui perturbe la conduite de l'engin. C'est notamment le cas en snowboard lors des appuis sur la carre arrière.When the upper portion of its cuff has a front face with reduced transverse curvature, support device makes it possible to execute figures which require strong lateral inclinations of the lower leg. However this device makes the rear supports less precise, which disrupts the operation of the vehicle. This is particularly the case in snowboard when pressing on the rear edge.

L'invention a notamment pour objet un dispositif d'appui arrière qui permet d'une part de fortes inclinaisons latérales du bas de jambe, et d'autre part des appuis arrière précis.The invention particularly relates to a support device rear which allows on the one hand strong lateral inclinations lower leg, and secondly precise rear supports.

Pour ce faire l'invention propose un dispositif d'appui arrière prévu pour être intégré à un ensemble de retenue d'une chaussure ou à une chaussure, le dispositif comprenant une manchette dont une portion inférieure est prévue pour être reliée à une embase de l'ensemble de retenue ou à la chaussure, et dont une portion supérieure est prévue pour s'étendre en regard du bas de jambe d'un utilisateur, la portion supérieure de la manchette ayant une face avant dont la courbure transversale est concave, la flèche de la courbure transversale se réduisant continûment du bas vers le haut de la portion supérieure.To do this, the invention proposes a support device rear intended to be integrated into a retaining assembly of a shoe or shoe, the device comprising a cuff of which a lower portion is intended to be connected to a base of the restraint system or to the shoe, and an upper portion of which is intended to extend in look of a user's lower leg, the upper portion of the cuff having a front face whose curvature transverse is concave, the arrow of the transverse curvature continuously reducing from the bottom to the top of the portion higher.

Le dispositif d'appui arrière selon l'invention est caractérisé par le fait qu'un renfort s'étend en hauteur le long de la portion supérieure, le renfort étant réalisé avec un matériau différent du matériau constitutif de la manchette. Le renfort rigidifie la portion supérieure, de façon à limiter sa flexion lors d'une sollicitation arrière par le bas de jambe. Il s'ensuit avantageusement que les appuis arrière sont précis.The rear support device according to the invention is characterized by the fact that a reinforcement extends in height the along the upper portion, the reinforcement being made with a material different from the material of the cuff. The reinforcement stiffens the upper portion, so as to limit its flexion during rear stress by the lower leg. It advantageously follows that the rear supports are precise.

D'autres caractéristiques et avantages de l'invention seront mieux compris à l'aide de la description qui va suivre, en regard du dessin annexé illustrant, selon un exemple non limitatif, comment l'invention peut être réalisée, et dans lequel :

  • la figure 1 est une vue en perspective arrière d'un ensemble de retenue d'une chaussure sur une planche, l'ensemble comprenant un dispositif d'appui arrière selon l'invention,
  • la figure 2 est une vue de côté partielle de l'ensemble de la figure 1,
  • la figure 3 est une vue en perspective éclatée avant d'un renfort et d'une manchette du dispositif d'appui arrière.
Other characteristics and advantages of the invention will be better understood with the aid of the description which follows, with reference to the appended drawing illustrating, according to a non-limiting example, how the invention can be implemented, and in which:
  • FIG. 1 is a rear perspective view of a shoe retaining assembly on a board, the assembly comprising a rear support device according to the invention,
  • FIG. 2 is a partial side view of the assembly of FIG. 1,
  • Figure 3 is an exploded perspective view before a reinforcement and a cuff of the rear support device.

Selon l'exemple illustré, un ensemble de retenue 1 est prévu pour retenir une chaussure non représentée sur une planche 2.According to the example illustrated, a retaining assembly 1 is provided for retaining a shoe not shown on a plate 2.

De manière connue comme on le voit sur la figure 1, l'ensemble de retenue 1 comprend une embase 3 qui s'étend en longueur entre une extrémité arrière 4 et une extrémité avant 5. L'embase 3 présente une face supérieure 6 prévue pour être en regard de la semelle de la chaussure, et une face inférieure 7 prévue pour être au-dessus de la planche 2. La face supérieure 6 est délimitée en largeur en partie au moins par un premier flasque 8 et par un deuxième flasque 9. Un arceau 10 relie les flasques 8, 9 l'un à l'autre du côté de l'extrémité arrière 4. As is known in FIG. 1, the retaining assembly 1 comprises a base 3 which extends in length between a rear end 4 and a front end 5. The base 3 has an upper face 6 designed to be opposite the sole of the shoe, and a lower face 7 intended to be above board 2. The face upper 6 is delimited in width at least in part by a first flange 8 and by a second flange 9. An arch 10 connects the flanges 8, 9 to each other on the end side rear 4.

De préférence l'embase 3, les flasques 8, 9 et l'arceau 10 forment une pièce monobloc, réalisée par exemple avec une matière synthétique. Cependant, il pourrait être prévu que les flasques ou l'arceau soient solidarisés à l'embase par d'autres moyens tels que des vis, des rivets, un collage, un emboítement, ou autre.Preferably the base 3, the flanges 8, 9 and the arch 10 form a single piece, made for example with a synthetic material. However, it could be expected that flanges or the arch are secured to the base by other means such as screws, rivets, bonding, interlocking, or other.

Des moyens de retenue sont prévus pour retenir la chaussure sur l'embase 3 de façon amovible.Retaining means are provided for retaining the shoe on base 3 removably.

Ces moyens sont représentés sous la forme de sangles 11, 12 qui s'étendent d'un flasque 8, 9 à l'autre. Chaque sangle peut être ouverte, fermée, serrée ou desserrée par tout moyen connu de l'homme du métier.These means are represented in the form of straps 11, 12 which extend from one flange 8, 9 to another. Each strap can be opened, closed, tightened or loosened by any means known to those skilled in the art.

Bien entendu les moyens de retenue de la chaussure pourraient être réalisés autrement. Par exemple il pourrait être prévu un ou plusieurs verrous fixés à l'embase et un ou plusieurs organes d'ancrage fixés à la chaussure, chaque organe d'ancrage pouvant être retenu par le verrou.Of course the shoe retaining means could be done otherwise. For example he could one or more locks fixed to the base and one or more several anchoring members attached to the shoe, each member anchor that can be retained by the bolt.

L'embase 3 est retenue sur la planche 2 par exemple à l'aide d'un disque 13, lui-même solidarisé à la planche par exemple par des vis 14.The base 3 is retained on the board 2 for example at using a disc 13, itself secured to the board by example with screws 14.

Bien entendu d'autres moyens de retenue de l'embase 3 sur la planche 2 pourraient convenir.Of course, other means of retaining the base 3 on Plate 2 could be suitable.

Un dispositif d'appui arrière, prévu pour que l'utilisateur prenne des appuis arrière avec le bas de jambe, est disposé au niveau de l'extrémité arrière 4 de l'embase 3.A rear support device, provided so that the user takes rear supports with the lower leg, is arranged at the rear end 4 of the base 3.

Le dispositif d'appui arrière comprend une manchette 20 qui s'étend en longueur entre une face arrière 21 et une face avant 22, en largeur entre un premier bord latéral 23 et un deuxième bord latéral 24, ainsi qu'en hauteur entre une extrémité inférieure 25 et une extrémité supérieure 26.The rear support device comprises a cuff 20 which extends in length between a rear face 21 and a face front 22, in width between a first lateral edge 23 and a second lateral edge 24, as well as in height between a lower end 25 and an upper end 26.

La manchette 20 est reliée à l'embase 3 par exemple au moyen d'une articulation, selon un axe transversal W. De manière non limitative, l'articulation de la manchette se fait à la frontière de l'arceau 10 et des flasques 8, 9.The cuff 20 is connected to the base 3 for example at the by means of a joint, along a transverse axis W. De in a nonlimiting manner, the articulation of the cuff is made at the border of the arch 10 and the flanges 8, 9.

L'utilisateur peut ainsi abaisser la manchette 20 vers l'embase 3 dans une position de rangement.The user can thus lower the cuff 20 towards the base 3 in a storage position.

Afin de limiter une rotation de la manchette 20 vers l'arrière une butée 30 est solidarisée à la manchette, au niveau de la face arrière 21, par un moyen représenté sous la forme d'une vis 31. La limitation de la rotation vers l'arrière se fait par appui de la butée 30 sur l'arceau 10.In order to limit rotation of the cuff 20 towards the rear, a stop 30 is secured to the cuff, to the level of the rear face 21, by a means shown under the shaped like a screw 31. Limiting backward rotation is done by pressing the stop 30 on the arch 10.

Bien entendu il peut être prévu des moyens de réglage de la position de la butée 30, dans le sens de la hauteur de la manchette 20, afin d'ajuster l'inclinaison de celle-ci.Of course, there may be provided means for adjusting the the position of the stopper 30, in the height direction of the cuff 20, in order to adjust the inclination thereof.

La position de la manchette 20 pour laquelle la butée 31 est en appui sur l'arceau 10 est une position qui permet la conduite de la planche 2.The position of the cuff 20 for which the stop 31 is supported on the arch 10 is a position which allows the driving the board 2.

Dans cette position, comme on le comprend mieux à l'aide de la figure 2, une portion inférieure 32 de la manchette 20 s'étend le long de l'arceau 10 d'un flasque 8, 9 à l'autre. La portion inférieure 32 est délimitée vers le bas par l'extrémité inférieure 25. La portion inférieure 32 est située en avant de l'arceau 10, mais il aurait pu être prévu qu'elle soit en arrière.In this position, as can be better understood using in FIG. 2, a lower portion 32 of the cuff 20 extends along the arch 10 from one flange 8, 9 to the other. The lower portion 32 is bounded downwards by the end lower 25. The lower portion 32 is located in front of the rollbar 10, but it could have been expected that it is in back.

Dans tous les cas, l'arceau 10 et la portion inférieure 32 sont à la hauteur de la cheville quand l'utilisateur conduit la planche, et sont concaves transversalement vers l'avant pour mieux entourer la cheville.In all cases, the arch 10 and the lower portion 32 are at ankle height when the user drives the board, and are concave transversely forward for better surround the ankle.

Une portion supérieure 33 de la manchette 20, qui prolonge cette dernière depuis la portion inférieure 32 jusqu'à l'extrémité supérieure 26, est quant à elle à la hauteur du bas de jambe quand l'utilisateur conduit la planche.An upper portion 33 of the cuff 20, which extends the latter from the lower portion 32 to the upper end 26, is in turn at the height of the bottom leg when the user is driving the board.

La portion supérieure 33 est en partie au moins concave transversalement vers l'avant, la flèche de la courbure transversale se réduisant continûment depuis le bas vers le haut de la portion supérieure 33.The upper portion 33 is partly at least concave transversely forward, the curvature arrow transverse reducing continuously from the bottom to the top of upper portion 33.

Il doit être compris que la flèche est la distance mesurée entre le milieu d'une courbe qui s'étend transversalement en suivant la face avant 22, et le milieu de la corde correspondante. La courbe est délimitée en longueur par deux extrémités dont l'une au moins est sur l'un des bords 23, 24, les deux extrémités étant contenues dans un même plan transversal.It should be understood that the arrow is the distance measured between the middle of a curve that extends transversely in along the front face 22, and the middle of the rope corresponding. The curve is delimited in length by two ends of which at least one is on one of the edges 23, 24, the two ends being contained in the same plane transverse.

Dans un cas où les bords 23, 24 dont symétriques par rapport à un plan vertical médian de la manchette, les deux extrémités de la courbe sont chacune sur un bord 23, 24. Dans un cas où un bord présente par exemple une excroissance vers l'avant, une extrémité de la courbe est sur un bord, l'autre extrémité étant sur la face avant 22.In a case where the edges 23, 24 of which are symmetrical by in relation to a median vertical plane of the cuff, the two ends of the curve are each on an edge 23, 24. In a case where an edge presents for example a protrusion towards the front, one end of the curve is on one edge, the other end being on the front face 22.

Selon l'invention la flèche de la courbure transversale est inférieure ou égale à 35 mm en bas de la portion supérieure 33, et diminue régulièrement pour atteindre une valeur inférieure ou égale à 10 mm en haut de la portion supérieure 33.According to the invention the arrow of the transverse curvature is less than or equal to 35 mm at the bottom of the upper portion 33, and decreases regularly to reach a value less than or equal to 10 mm at the top of the upper portion 33.

La représentation graphique de la valeur de la flèche en fonction de sa position le long de la manchette 20, dans un repère orthonormé, est de préférence une droite. La flèche de la courbure transversale varie linéairement le long de la portion supérieure 33. Cependant, la représentation graphique pourrait être une courbe incurvée vers le haut ou vers le bas, la variation de la flèche étant dans ce cas non linéaire.The graphical representation of the value of the arrow in depending on its position along the cuff 20, in a orthonormal coordinate system, is preferably a straight line. The arrow of the transverse curvature varies linearly along the upper portion 33. However, the graphical representation could be an upward or downward curved curve, the variation of the deflection being in this case nonlinear.

Par exemple pour une portion supérieure 33 haute d'environ 150 mm, la flèche en bas de la portion est voisine de 35 mm, la flèche au milieu de la hauteur est voisine de 12 mm, et la flèche mesurée à 20 mm de l'extrémité supérieure 26 est voisine de 5 mm.For example for a top portion 33 high of approximately 150 mm, the arrow at the bottom of the portion is close to 35 mm, the arrow in the middle of the height is close to 12 mm, and the arrow measured 20 mm from the upper end 26 is close 5 mm.

Ces valeurs de flèches confèrent à la face avant 22 une concavité transversale réduite, dans la portion supérieure 33. Ainsi l'utilisateur peut facilement incliner le bas de jambe dans une direction transversale. Cela lui permet d'exécuter des figures qui nécessitent de fortes inclinaisons latérales des jambes.These arrow values give the front face 22 a reduced transverse concavity, in the upper portion 33. So the user can easily tilt the lower leg in a transverse direction. This allows him to execute figures which require strong lateral inclinations of the legs.

Il est par ailleurs prévu un renfort 40 qui s'étend en hauteur le long de la portion supérieure, de préférence depuis une limite 41 pour laquelle la flèche de la courbure transversale est inférieure ou égale à 20 mm, et jusqu'à ou à proximité du haut de la portion supérieure 33.There is also provided a reinforcement 40 which extends in height along the upper portion, preferably from a limit 41 for which the deflection of the curvature transverse is less than or equal to 20 mm, and up to or near the top of the upper portion 33.

Comme on le comprend mieux à l'aide de la figure 3, le renfort 40 présente la forme d'un coin évidé. Ce dernier s'étend en hauteur le long de la portion supérieure 33, depuis une base 42 jusqu'à une pointe 43.As can be better understood using Figure 3, the reinforcement 40 has the shape of a hollow corner. This last extends in height along the upper portion 33, from a base 42 to a point 43.

Le renfort 40 comprend une enveloppe 44 qui délimite une paroi arrière 45 et deux parois latérales 46, 47 du renfort. L'enveloppe 44 délimite également une cavité 48 ouverte vers l'avant. Dans tous les cas, le renfort 40 est réalisé avec un matériau différent du matériau constitutif de la manchette 20. The reinforcement 40 comprises an envelope 44 which delimits a rear wall 45 and two side walls 46, 47 of the reinforcement. The envelope 44 also delimits a cavity 48 open towards forward. In all cases, the reinforcement 40 is produced with a material different from the material of the cuff 20.

L'enveloppe est de préférence réalisée à partir d'une tôle métallique emboutie et découpée à la presse. Par exemple une tôle d'acier inoxydable ou d'alliage d'aluminium, dont l'épaisseur est voisine de 1 mm, convient très bien.The envelope is preferably made from a sheet metallic stamped and cut with a press. For example a stainless steel or aluminum alloy sheet, of which the thickness is close to 1 mm, is very suitable.

La manchette 20 est quant à elle réalisée de préférence à partir d'une matière plastique.The cuff 20 is preferably made of from plastic.

Le renfort 40 est disposé sensiblement selon une ligne verticale médiane de la manchette 20, en appui sur la face arrière 21.The reinforcement 40 is disposed substantially along a line vertical middle of the cuff 20, bearing on the face rear 21.

Pour retenir le renfort 40 à la manchette 20, il est prévu par exemple quatre pattes 55 issues des parois latérales 46, 47. Les pattes 55 sont glissées chacune dans une fente 56 de la manchette 20, puis repliées chacune dans une cavité 57 de la face avant 22.To retain the reinforcement 40 at the cuff 20, it is provided for example four legs 55 from the side walls 46, 47. The legs 55 are each slid into a slot 56 in the cuff 20, then folded each into a cavity 57 of the front panel 22.

Bien entendu le nombre de pattes, de fentes et de cavités pourrait être différent.Of course the number of legs, slots and cavities might be different.

Encore, d'autres moyens pourraient convenir pour solidariser le renfort 40 à la manchette 20, comme de la colle, des vis, des rivets ou autre.Still, other means may be suitable for secure the reinforcement 40 to the cuff 20, like glue, screws, rivets or whatever.

Les dimensions du renfort 40 sont de préférence les suivantes :

  • la largeur de la base 42 est comprise entre 10 et 60 mm,
  • l'épaisseur au niveau de la base est comprise entre 5 et 25 mm, l'épaisseur devant être comprise comme étant la distance entre la paroi arrière 45 du renfort 40 et la partie la plus avancée des parois latérales 46, 47,
  • la largeur de la pointe 43 est comprise entre 10 et 40 mm,
  • l'épaisseur au niveau de la pointe est comprise entre 2 et 10 mm.
The dimensions of the reinforcement 40 are preferably the following:
  • the width of the base 42 is between 10 and 60 mm,
  • the thickness at the base is between 5 and 25 mm, the thickness to be understood as being the distance between the rear wall 45 of the reinforcement 40 and the most advanced part of the side walls 46, 47,
  • the width of the point 43 is between 10 and 40 mm,
  • the thickness at the tip is between 2 and 10 mm.

La hauteur du renfort 40, mesurée entre la base 42 et la pointe 43, est comprise de préférence entre 50 et 100 mm.The height of the reinforcement 40, measured between the base 42 and the tip 43, is preferably between 50 and 100 mm.

Dans le cas où la portion supérieure 33 de la manchette 20 fait 150 mm de haut, la base 42 du renfort 40 est sensiblement à 90 mm de l'extrémité supérieure 26, et le renfort mesure environ 70 mm de haut. Pour le même cas, la largeur de la base 42 est voisine de 36 mm, l'épaisseur de la base est voisine de 11 mm, la largeur de la pointe 43 est voisine de 10 mm, et l'épaisseur de la pointe est voisine de 3 mm. In the case where the upper portion 33 of the cuff 20 is 150 mm high, the base 42 of the reinforcement 40 is substantially 90 mm from the upper end 26, and the reinforcement measures about 70 mm high. For the same case, the width of the base 42 is close to 36 mm, the thickness of the base is close to 11 mm, the width of the point 43 is close to 10 mm, and the thickness of the tip is close to 3 mm.

De par sa localisation et sa structure, le renfort 40 confère au dispositif d'appui arrière une résistance mécanique en flexion qui permet des appuis arrière précis. L'affaiblissement mécanique en flexion de la manchette 20, qui résulte de la faible concavité transversale de la portion supérieure 33, est compensée par l'adjonction du renfort 40.By its location and its structure, the reinforcement 40 gives the rear support device mechanical resistance in flexion which allows precise rear support. The mechanical weakening in bending of the cuff 20, which results from the low transverse concavity of the portion upper 33, is offset by the addition of reinforcement 40.

Le dispositif d'appui arrière selon l'invention est léger, car la cavité 48 du renfort 40 confère à ce dernier une masse réduite.The rear support device according to the invention is light, because the cavity 48 of the reinforcement 40 gives the latter a mass scaled down.

D'une manière générale, le dispositif d'appui arrière et l'ensemble de retenue 1 selon l'invention sont fabriqués à partir de tous les matériaux et selon toutes les techniques connues de l'homme du métier.In general, the rear support device and the restraint assembly 1 according to the invention are manufactured at from all materials and using all techniques known to those skilled in the art.

En particulier, la manchette 20 est de préférence réalisée à partir d'une matière synthétique, telle que du polypropylène, du polyamide, du polyuréthanne ou autre.In particular, the cuff 20 is preferably made from a synthetic material, such as polypropylene, polyamide, polyurethane or the like.

Bien entendu, l'invention n'est pas limitée à l'exemple ci-avant décrit, et comprend tous les équivalents techniques pouvant entrer dans la portée des revendications qui vont suivre.Of course, the invention is not limited to the example described above, and includes all technical equivalents which may fall within the scope of the claims which to follow.

En particulier le renfort disposé sur la manchette peut présenter des formes très diverses, et avoir une structure pleine.In particular, the reinforcement placed on the cuff can present very diverse forms, and have a structure full.

Le renfort peut aussi former avec la manchette une pièce monobloc.The reinforcement can also form with the cuff a piece piece.

Il pourrait encore être prévu plusieurs renforts sensiblement parallèles les uns aux autres. Ces renforts seraient répartis sur la face arrière 21 de la manchette, et disposés de préférence de façon symétrique par rapport à un plan vertical médian.Several reinforcements could still be provided substantially parallel to each other. These reinforcements would be distributed over the rear face 21 of the cuff, and preferably arranged symmetrically with respect to a vertical median plane.
